How to handle Autocomplete in Java-Webdriver

Below partial text of definition is copied from Wikipedia http://en.wikipedia.org/wiki/Autocomplete

 
Definition: Autocomplete involves the program predicting a word or phrase that the user wants to type in without the user actually typing it in completely. This feature is effective when it is easy to predict the word being typed based on those already typed, such as when there are a limited number of possible or commonly used words

Below is the sample program to demonstrate 'google search' autocomplete feature.

Program:

package wd;

import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class WDAutoCompleTest {

    static WebDriver driver = null;
    static String URL = "http://www.google.com/";
    static String SEARCH_FOR = "java webdriver api";
    static String TYPE_SEARCH_TEXT = "java webdrii";
    public static void main(String[] args) throws Exception {
        //Launch the browser with the URL provided.
        launchURL();
       
        //Enter the searchText.
        WebElement webElement = driver.findElement(By.id("gbqfq"));
        webElement.sendKeys(TYPE_SEARCH_TEXT);
        webElement.sendKeys(Keys.BACK_SPACE);
        Thread.sleep(1000);
       
        List<WebElement> list = driver.findElements(By.xpath("//div[@class='sbsb_a']/ul/li"));
        int i=1;
        for(WebElement webElementLiList : list){
            if(!(i<=list.size())) break;
            WebElement webElementLi = webElementLiList.findElement(By.xpath("//div[@class='sbsb_a']/ul/li["+i+"]/div/div[2]"));
            String text = webElementLi.getText();
            if(text.equalsIgnoreCase(SEARCH_FOR)){
                System.out.println("Search String :: "+text);
                webElementLi.click();
                break;
            }
           
            i++;
        }
       
        //Close the browser & webdriver
        quitDriver();
    }
   
    public static void launchURL() throws InterruptedException{
        driver = new FirefoxDriver();
        driver.manage().window().maximize();
        driver.get(URL);
        Thread.sleep(1000);
    }
   
    public static void quitDriver() throws InterruptedException{
        Thread.sleep(5000);
        driver.close();
        driver.quit();
    }

}

Output:
